Overview
- Hochtief will join Germany’s DAX and replace Porsche Automobil Holding SE on June 22, with ISS Stoxx confirming the quarterly index reshuffle after its May rankings.
- The construction group earned promotion after its share price almost tripled over the past year and its market value exceeded €38 billion despite only about 22.5% free float held mainly by ACS.
- Porsche SE will move to the MDAX and says the downgrade is a technical outcome that does not change its business fundamentals after a near‑€1 billion Q1 writedown on its Volkswagen stake.
- The MDAX will also admit three semiconductor‑linked firms — Elmos, Siltronic and Suss Microtec — while several mid‑ and small‑caps shift into the SDAX and Lufthansa narrowly missed returning to the DAX.
- Passive index trackers must rebalance holdings to match the new line‑up, a flow that can push affected share prices and change which companies get greater visibility from international investors.
